Lumps somehow led us on (7)

Ross

I believe the answer is:

nodules

'lumps' is the definition.
(a nodule is a lump of cells in the body)

'somehow led us on' is the wordplay.
'somehow' is an anagram indicator.
'led'+'us'+'on'='leduson'
'leduson' with letters rearranged gives 'NODULES'.

(Other definitions for nodules that I've seen before include "Small swellings" , "Loudens like lumps" , "Loudens due to small lumps" , "Small rounded lumps" , "Small lumps - led us on (anag)" .)

I've seen this clue in The Independent.
